Faisal, You don't need to worry about power range when connecting SR or LR. However, an ER or ZR on a loopback can damage Rx. The strength of the receiving signal is always under the tolerance allowed. The 850nm Light is attenuated very quickly because of the MMF and the 850nm light source. This

Thank You Bob Evans CTO Hello, I was looking for feedback on the following question:- When connecting two MM SFP/SFP+/XFP 's together...(short range). What should be the best practice receive power range ? Is it true that if the rx power is higher than (x?) then it shortens the life
